NWS Kansas City, MO wrote its last area forecast discussion before the first event at May 8, 5:06 PM CST, 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 606 PM CDT Thu May 8 2014 .DISCUSSION... Issued at 246 PM CDT THU MAY 8 2014 Still expect convective initiation to occur over the next few hours along a cold front which is moving into eastern KS this afternoon. Shower activity over MO has been light in coverage and intensity, so airmass to the east of the front has not stabilized too significantly. Aircraft soundings out of MCI still indicate a weak capping inversion near 850 hPa where temperatures are around 16C. These will need to cool to around 14C to reduce inhibition enough for thunderstorms to develop, and most models indicate this will occur over the next couple of hours as the upper trough approaches from the west. Still believe storms are likely to initiate close to or just west of a Maryville to Topeka line later this afternoon, and approach the I-35 corridor near or just after 7 PM. Temperatures rising into the upper 70s and lower 80s across eastern KS will allow CAPE values to rise into the 1000 to 1500 J/kg range through the afternoon, potentially higher. This combined with 0-6km shear values between 40 and 50 kt will allow for some of these storms to become severe with large hail and damaging winds. Storms will likely reach their peak severity across a corridor from near Lawrence to St. Joseph and Maryville where the greatest instability exists, and storms here could briefly become supercells with very large hail and perhaps an isolated tornado. The severe threat will decrease further east toward I-35 where storms may take the form of a line with hail and scattered damaging winds, and even lower probabilities of severe storms exist to the east of US 65. Most precipitation will exit the area toward midnight as the cold front pushes into central Missouri. However, a secondary mid-level shortwave rounding the base of the primary upper trough could provide another wave of showers and thunderstorms from eastern KS into western and central MO late tonight and early Friday. Best chances to see this activity will be south of I-70. Elevated instability by this time will be minimal so storms should stay below severe limits, although with continued strong deep-layer shear it wouldn't be surprising to see some small hail with these storms. The frontal boundary will stall over the Ozarks Friday night and return north over the weekend. This will set the stage for a potentially active period Saturday afternoon through Monday as a deepening trough to the west sends multiple impulses into the region. This could result in several rounds of thunderstorms as these waves interact with the quasi-stationary frontal boundary. The first round of storms could develop as early as Saturday afternoon when most models bring the warm front into Iowa leaving the entire forecast area warm and unstable. Will need to watch for some strong storms given potentially strong instability, but marginal shear and a lack of a defined forcing mechanism should prevent a widespread severe threat on Saturday. By Saturday night and Sunday morning a more significant threat for widespread thunderstorms will exist as a strong low-level jet noses into eastern KS and western MO and interacts with the boundary in place. NAM is a particularly interesting solution with very strong moisture transport advecting toward the boundary which results in several inches of rain near the MO River. Whether this heavy rain threat is actually realized is dependent on a lot of factors including location of the front and magnitude of the low- level jet. So it's too early to say if heavy rain and severe thunderstorms are a real possibility Saturday night and early Sunday but it certainly bears watching. Additional thunderstorms are possible Sunday afternoon through Monday as the upper trough to the west deepens and a cold front moves through the area. Severe potential this period will depend on the exact timing of the front, airmass destabilization in the wake of earlier storms and wind fields ahead of the upper trough which won't be known for a few days. Forecast becomes more benign by midweek with cyclonic upper-level flow bringing drier conditions and cooler temperatures. && .AVIATION...(For the 00Z TAFS through 00Z Friday Evening) Issued at 604 PM CDT THU MAY 8 2014 VFR conditions expected during the TAF period. Scattered thunderstorms will move over/near terminals now through 03Z. A brief reduction of ceilings/visibility may be possible in the heaviest activity. Otherwise, conditions are expected to gradually improve during the late evening/overnight, with a wind shift out of the west- northwest. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE.
